[CRIU] [PATCH v4 0/9] mount: make it possible to dump overmounted mount

[Pavel Tikhomirov]

For our use case and explanation how we fix it - see patch 04.

We already have a test for it tempfs_overmounted, just remove crfail.

v4: Add additional fixes for mnt_resort_siblings, try_remap_mount,
does_mnt_overmount so that we can make tmpfs_overmounted test even
better.

Pavel Tikhomirov (9):
  mount: add mnt_is_overmounted helper to check mount visibility
  mount: add __umount_children_overmounts helper to make mount visible
  mount add umount_overmounts helper to make mount visible
  mount: make open_mountpoint handle overmouts properly
  zdtm: now tempfs_overmounted will pass so remove crfail
  mount: fix mnt_resort_siblings to work as described
  mount: fix try_remap_mount
  mount: do remaps for child-overmount of another overmount
  zdtm: improve tempfs_overmounted test
